FlatOut Off Road Multi-Purpose Tire Sealant - Prevents and Repairs Flat Tires - Seals Leaks - Contains Kevlar - Tubeless Tire Sealant - 32-Ounce Bag - Pack of 2

Updated 2023:Im now on my 4th bottle of this stuff and increased the star rating. Ive got it in all 4 lawnmower tires, both tires on the lawnmower trailer, and in the wheelbarrow tire. Ive never had a single leak since. We've got a lot of thorns in our yard that are hard to see and I'd had my fill of patching them. After seeing how well this worked on the lawnmower, I keep putting it in any yard tire that gets a flat and they all hold air permanently from then ok. The product 100% works as advertised.I still think its pricey (but saves you on time dealing with future flats) and still hate the cheap stem removal tool (luckily I saved the metal one I bought when the original broke on me). I also hate the new container - it refuses to stay upright. But the product itself works so well that its worth overlooking all of these things.Original review:Used in a lawnmower. Have some thorns on the property that occasionally puncture tires, so I often have at least 1 tire losing air. Used to pull and patch, but thats a pain to keep up with.Tried this for a plan B to hopefully stop the constant patching and so far its holding up great after a month. Easy to put in the tires with the instructions.Two downsides:-Cost is a bit high considering usage. I didn't read carefully before ordering, but it takes 1 bottle for the 2 fronts + 1 bottle for each rear. I haven't bought it for the rears yet as I'm reluctant to spend that much more money.-The valve stem remover included is absolute garbage. It barely removed the 1st one when it cracked. Couldn't reinstall the 1st or remove the 2nd at all as it disintegrated. Had to go buy a metal tool from the store mid project. IMO they shouldn't even include it if they're going to out such a cheap one on it.

this stuff really works, i've been using this product for a while in most of my vehicles and bikes and no flats yet keeping my fingers crossed that it stay that way.

Worked great and easy to use

Flat Out Keeps Our New E-Bikes Rolling!We recently purchased a pair of e-bikes and are thrilled to hit the trails! Being new to e-bikes, we also wanted some peace of mind when it comes to flats. That's why we decided to try Flat Out Tire Sealant for the first time.So far, so good! Installing Flat Out was a breeze following the instructions, and it only took a few minutes per tire. We're happy to report that after riding approximately 250 miles, we haven't encountered any flats yet!Here's what we're loving about Flat Out:The product claims: Fewer roadside repairs. No one enjoys fixing a flat, especially on an e-bike. Flat Out hopefully means we can spend less time tinkering and more time enjoying the ride (and we have for 250 miles so far!).Increased confidence: Knowing the sealant is there offers some peace of mind, allowing us to explore further without worrying about flats interrupting our adventure.Long-lasting protection: The product claims to last for over 10 years, which is a great value.We'll be sure to update this review after even more miles on the e-bikes, but with 250 miles under our belt and no flats, Flat Out seems like a great way to help prevent flats and keep our e-bike adventures rolling smoothly. We recommend it to any new (or seasoned) e-bike rider looking for some added puncture protection!

FlatOut works well. Old timer kept pinching holes in the motorbike tube putting the tire back on the rim. It was getting me almost to tears. I put this in before I tried another new tube, it did not work. The pinched holes were up too high near the rim. I added more FlatOut, no luck. I added the rest of the quart, and it held some air for a while. I added air again and it held, and held, and held for a few months. It's a whole nother story when it let go under me, out on the road. Next time I got the new tube in, without pinching a hole in it.

Incredible product. I’ve gone 800 miles on my e-bike after getting a glat. The tube and tire got a massive nail right through it and it just keeps going. However, the tool that removes the valve stem is awful, it’s cheap plastic that just breaks when you remove the valve stem if you even can which I couldn’t the second tire. You will likely need to use another tool. But the sealant is amazing so still 5 stars

Just got it for my new ebike. However, the tires already has slime in them. Will wait until I have to refill the tires. I hear this is the best product on the market.

Although it changes the smooth cruise of the terrain , it will save an expensive stock of intertubes.

Save me alot on my ebike. You need to put about the exact amount. If not the product is not good.

As described

It does not seal inner tube punctures.

I used it to protect my electric bicycle 4” wide tires from getting a terrible flat while riding out on the trail

I must admit I was sceptical about purchasing this item to fix my ride on lawn mower tyre but it is brilliant. That good I will be buying some more.
